I don't use steam but it'd be nice for Valve to show MS how to properly let their users share games.

LOL.

In all seriousness, it'd be great to have a digital service like valve offering something that's also being touted on Xbox One, because if MS is the only outlet doing it, they'll probably do it wrong. I trust Valve to show how it's done right.
